Step-by-step math

Every number below is computed from the input, nothing is looked up.

1. sRGB → linear

R: 192/255 = 0.75294 → 0.527115  (((x + 0.055) / 1.055)^2.4)
G: 132/255 = 0.51765 → 0.230740  (((x + 0.055) / 1.055)^2.4)
B: 252/255 = 0.98824 → 0.973445  (((x + 0.055) / 1.055)^2.4)

2. linear sRGB → LMS

l = 0.4122·R + 0.5363·G + 0.0514·B = 0.391121
m = 0.2119·R + 0.6807·G + 0.1074·B = 0.373307
s = 0.0883·R + 0.2817·G + 0.6300·B = 0.724799

3. cube root

l′ = ∛0.391121 = 0.731314
m′ = ∛0.373307 = 0.720038
s′ = ∛0.724799 = 0.898268

4. LMS′ → Oklab

L = 0.2105·l′ + 0.7936·m′ − 0.0041·s′ = 0.72169
a = 1.9780·l′ − 2.4286·m′ + 0.4506·s′ = 0.10261
b = 0.0259·l′ + 0.7828·m′ − 0.8087·s′ = -0.14384

5. Oklab → OKLCH

C = √(a² + b²) = 0.17669
H = atan2(b, a) = 305.504°
L = 0.72169

6. OKLCH

oklch(0.72169 0.17669 305.504)
rounded: oklch(0.722 0.177 305.5)
